NAME

SYNOPSIS

DESCRIPTION

The pkcs7 command processes PKCS#7 files in DER or PEM format.

COMMAND OPTIONS

-informDER|PEM
This specifies the input format. DER format is DER encoded PKCS#7
v1.5 structure.PEM (the default) is a base64 encoded version of the
DER form with header and footer lines.
-outformDER|PEM
This specifies the output format, the options have the same meaning
as the -inform option.
-infilename
This specifies the input filename to read from or standard input if
this option is not specified.
-outfilename
specifies the output filename to write to or standard output by
default.
-print_certs
prints out any certificates or CRLs contained in the file. They are
preceded by their subject and issuer names in one line format.
-text
prints out certificates details in full rather than just subject
and issuer names.
-noout
don't output the encoded version of the PKCS#7 structure (or
certificates is -print_certs is set).
-engineid
specifying an engine (by its unique id string) will cause pkcs7 to
attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the
default for all available algorithms.

EXAMPLES

NOTES

The PEM PKCS#7 format uses the header and footer lines:
-----BEGIN PKCS7-----
-----END PKCS7-----
For compatibility with some CAs it will also accept:
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----

RESTRICTIONS

There is no option to print out all the fields of a PKCS#7 file.
This PKCS#7 routines only understand PKCS#7 v 1.5 as specified in
RFC2315 they cannot currently parse, for example, the new CMS as
described in RFC2630.
